The 49-year-old actor - whose daughter Jane gave birth to baby Jackson in February - explained the tot is "very funny" and will employ all kinds of tactics to get out of eating his meals.

He said: "He`s got this mischief on his face that you can just tell that he knows he`s going to be completely accepted in every way, you know? It`s just full on, `I am it. I know you want to see me. I know whenever I say hi, everybody`s going to laugh`.

"But he`s very funny, too. Yesterday it was the sunglasses, putting the sunglasses upside down. And that totally reminded me of me because I was a very finicky eater, and my mother said that I got out of eating every time by just making everybody laugh and everybody howl at the table."

It could be that Jackson is following in the star`s footsteps as Jim admitted he used to look up to his own father for comedic inspiration because he was one of the "funniest human beings" he`s ever met.

Jim added to Babble: "Since I was a little tiny kid, I used to look at my dad, and he used to command the room. And he was one of the funniest human beings you`ve ever met in your life.

"He was just one of these characters that when he told a story, he was so incredibly animated. The character I played in `The Truman Show` was my father."
